Funambol and Laszlo Systems.

Laszlo Systems, meanwhile, makes a web-based communications suite that includes email, contacts, and calendar. Laszlo is based in San Mateo, Calif.
The companies say that carriers can offer the integrated products to users for free and generate ad revenue as a result. Funambol says its software is available to 1.5 billion mobile phone users, though it doesn't say how many users it has. The integrated software is available at either company's web site.
In March, Laszlo raised $6. 6 million in a third round of funding from existing investors including: WI Harper Group, General Catalyst Partners, Sofinnova Ventures, Mitsui & Co.
